SSS similarity theorem states: If the corresponding sides of two triangles are proportional, then the two triangles are similar.
You have two isosceles triangle, then if
[tex]\dfrac{44}{20}=\dfrac{x}{35},\\ \\x=\dfrac{44\cdot 35}{20}=11\cdot 7=77,[/tex]
two isosceles triangles will be similar by SSS theorem.
Answer: correct choice is C.
The value of x that will make the triangles similar by SSS similarity theorem is;
x = 77.
We are told that the 2 triangles are similar by SSS theorem.
Now, SSS means Side - Side -Side and it is a congruence theorem which states that the 3 corresponding sides of two triangles have same ratio, then we can say that the two triangles are congruent by SSS theorem
Thus, in our 2 given triangles ,applying the SSS postulate gives;
x/35 = 44/20
Applying the multiplication property of equality, let us multiply both sides by 35 to get;
x = (44 * 35)/20
x = 77
Thus, in conclusion the value of x that will make the triangles similar by SSS similarity theorem is 77.

Which of the binomials below is a factor of this trinomial?
4x2 + 20x - 24
A. x + 4
B. x + 1
C. x - 1
D. x - 4
Answer: the correct option is (C) x - 1.
Step-by-step explanation: We are given to select the correct binomial that is a factor of the following trinomial :
[tex]T=4x^2+20x-24~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To select the factor, we need to factorize expression (i). To factorize, we need two integers with sum 20 and product -96.
From (i), we have
[tex]T\\\\=4x^2+20x-24\\\\=4x^2+24x-4x-24\\\\=4x(x+6)-4(x+6)\\\\=(x+6)(4x-4)\\\\=4(x+6)(x-1).[/tex]
So, the factors of the given trinomial are 4, (x + 6) and (x - 1).
Since 4 and ( x + 6) are not in the options, so (x - 1), is the correct binomial.
Thus, (C) is the correct option.
Write the quadratic equation in factored form. Be sure to write the entire equation. x2 - 5x - 24 = 0
x² - 5x - 24 = 0
First, we have to solve the quadratic equation and find the two values of x that fit the equation.
[tex]x = \frac{5+- \sqrt{5^{2} + 4*1*24 } }{2*1} = \frac{5+- \sqrt{25 + 96} }{2} = \frac{5+- \sqrt{121} }{2} = \frac{5+-11}{2} [/tex]
There are two values of x that fit:
x₁ = (5+11)/2 = 16/2 = 8
x₂ = (5-11)/2 = -6/2 = -3
Now I can restate the original equation in terms of a product of factors, with this product being equal to zero:
(x - x₁) * (x - x₂) = 0
ANSWER (x-8) * (x+3) = 0
Now I can solve each factor by setting each one equal to zero and solving the resulting linear equations:
x - 8 = 0 or x + 3 = 0
x = 8 or x = -3
We can check that these two values are the solution to the original quadratic equation.
x² - 5x - 24 = 0
First value
8² -5*8 -24 = 0
64 - 40 -24 = 0
0 = 0 ¡Checked!
Second value
(-3)² -5(-3) -24 = 0
9 + 15 -24 = 0
0 = 0 ¡Checked!
Hope this helps!

t takes Dariya 35 seconds to download 5 songs from the Internet. How can the number of seconds it would take Dariya to download 7 songs at this rate be determined?
Answer:
The time it takes to download 7 songs is 49 seconds.
Step-by-step explanation:
It is about a division problem.
The first step is to determine how long it takes to download just one song. You must divide the total seconds by the total songs downloaded. The result would be the time required to download just one song.
[tex]\frac{35\, seconds}{5\, songs}=7\frac{seconds}{song}[/tex]
The previous value indicates that the download time is 7 seconds per song.
The second step is to determine how long it takes to download 7 songs. With the previous value in mind, you must multiply the time it takes to download one song by the 7 songs that Dariya wants to download, to obtain the total time it takes to download the 7 songs.
[tex]\frac{7\, seconds}{1\, song}\times 7\, songs=49\, seconds[/tex]
Thus, the time it takes to download 7 songs is 49 seconds.
When visiting Baltimore, MD, you need to rent a taxi to get from your hotel to the National Aquarium. The taxi company charges a flat fee of $3.00 for using the taxi and $0.75 per mile. Write an equation in slope- intercept form that models this situation.
Answer:
The slope- intercept form this situation is given by y = 0.75x + 3 .
Step-by-step explanation:
The slope- intercept is given by
y = mx + c
Where m is the slope, c is the y intercept .
As given
When visiting Baltimore, MD needs taxi to get from your hotel to the National Aquarium.
The taxi company charges a flat fee of $3.00 for using the taxi and $0.75 per mile.
Let us assume that the total amount charge by the taxi be y .
Let us assume that the number of miles travelled by the taxi be x.
Than
Total amount charge by taxi = Amount charge by the taxi per miles + Flat free charge .
y = 0.75x + 3
(Here m = 0.75 and c = 3)
Therefore the slope- intercept form this situation is given by y = 0.75x + 3 .
The equation that models this situation is y = 0.75x + 3.
To write an equation in slope-intercept form that models the situation of renting a taxi in Baltimore, MD, you can use the following equation:
Total Cost (C) = (Cost per Mile) * (Number of Miles) + (Flat Fee)
In this case, the cost per mile is $0.75, and the flat fee is $3.00. So, the equation becomes:
C = 0.75x + 3.00
Here, C represents the total cost of the taxi ride, and x represents the number of miles traveled. This equation is in slope-intercept form (y = mx + b), where:
"C" is the dependent variable (y),
"x" is the independent variable (the number of miles traveled),
0.75 is the slope (m), which represents the cost per mile, and
3.00 is the y-intercept (b), which represents the flat fee.

A whale has a tracking device attached to it. The whale traveled 184 miles in 6 hours. About how fast did the whale swim per hour?
Final answer:
To find the whale's average speed per hour, divide the total distance of 184 miles by the time of 6 hours, resulting in an average speed of approximately 30.67 miles per hour.
Explanation:
The question asks for the speed of a whale per hour based on a certain distance traveled over a period of time. To calculate the speed of the whale, we can use the formula:
Speed = Distance ÷ Time
In this case, the whale traveled 184 miles in 6 hours. Using the formula, we divide 184 miles by 6 hours:
Speed = 184 miles ÷ 6 hours = 30.67 miles per hour
So, the whale swam at an average speed of about 30.67 miles per hour.

A girl stands 160 cm tall she stands 360 cm away from a lamp post at night her shadow from the light is 90 cm long how high is the lam post
Final answer:
To find the height of the lamppost given the girl's height, distance from the lamp post, and shadow length, set up a proportion to calculate the lamp post's height.
Explanation:
A girl stands 160 cm tall and stands 360 cm away from a lamp post at night. Her shadow from the light is 90 cm long. How high is the lamppost?
Set up a proportion: Lamp post height / Girl's height = Lamp post shadow length / Girl's shadow length.
Substitute the values: Lamp post height / 160 cm = 360 cm / 90 cm.
Solve for the lamp post height: Lamp post height = (360 cm * 160 cm) / 90 cm = 640 cm.
A pair of diamond earrings has been marked up 50% and is now selling for $198.00. How much were the earrings before the mark-up?
Final answer:
The original price of the diamond earrings before a 50% markup that led to a final selling price of $198.00 was $132.00.
Explanation:
The question asks us to find the original price of the diamond earrings before a 50% markup that resulted in a final selling price of $198.00. To solve this, we use the markup formula, which is Final Price = (Original Price) × (1 + Markup Percentage). Here, the Final Price is $198.00 and the Markup Percentage is 50%, or 0.50 when expressed as a decimal.
First, we rearrange our formula to solve for the Original Price:
Original Price = Final Price ÷ (1 + Markup Percentage). Plugging in the given values, we have: Original Price = $198.00 ÷ (1 + 0.50) = $198.00 ÷ 1.50.
Doing the computation: Original Price = $132.00. Therefore, the earrings were priced at $132.00 before the 50% markup.
